To all whom it may concern Be it known that we, FREDERICK J. HAR- RISONand WILLIAM J. KNOX, citizens of the United States, residing at Dubois,Pennsyl- Vania, have invented a certain new and useful Improvement inLocomotive-Pilots, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a plan view of a locomotive pilot of our improvedconstruction.

Fig. 12is an end elevational view of a modified form of our improved pilot.Fig. 13 is a front elevational view of the end portion of the form ofpilot seen in Fig. 12.

Our invention relates to new and useful improvements in locomotivepilots of the type shown in Patent No. 1,071,155, issued to us August26, 1913, the principal objects of our present invention being togenerally improve upon and simplify the constructions disclosed in thepatent aforesaid, and to form the main body of the pilot in two, or moreparts, which are preferably cast. Thus the manufacture of the pilots isgreatly simplified and cheapened for the reason that two or morecomparatively small castings can be produced much more readily and withconsiderable less expense than a single large casting, and furthermore,in the event of damage to one side of the pilot by collision, derailmentor from other cause, the damaged portion may be replaced and theundamaged portion continued in service.

Further objects of our invention are; to provide simple means forrigidly attaching the pilot to the bumper beam, which attach ing meanspermits the pilot to be readily and accurately adjusted vertically tosuit different conditions; to provide simple means for relieving thepilot attaching bolts from all shearing strains due to the weight of thepilot, and further, to form integral with the end portions of the pilot,a series of projecting brackets which serve as steps to meet therequirements of certain rules and regulations of the Interstate CommerceCommission, said steps serving as means whereby trainmen can readilyreach the bumper beam from the ground.

With the above and other objects in view, our invention consists incertain novel features of construction and arrangement of partshereinafter more fully described and claimed.

The form of pilot illustrated in Figs. 1 to 4 inclusive, consists of twointegral half members A and B, which are preferably cast, one right andone left, and being united at a vertical center line by rivets, bolts orby electric welding.

Each half member comprises a base 1, an upright end member or post 2, ahorizontally disposed top rail 3, a vertically disposed plate 4, aninner end or half center slat 5, and a series of intermediate inclinedslats 6 between the slat 5 and post 2, and extending from the basemember 1 and rail 3. The

base member 1 occupies a horizontal plane and is inclined or positionedat an angle with respect to the vertical plane occupied by the end railor post 2 and top rail 3.

The half center slat 5 on one of the half members of the pilot isprovided along its lower edge with a laterally projecting lip or flange5 which receives and supports the half center slat of the oppositesection. (See Fig. 4.)

In the drawings, the half slats 5 are shown connected by means ofrivets, but it will be readily understood that these parts may beconnected in any suitable manner either by bolts or by being welded. Theupslot are alternately disposed, z. e.

per portions of the end posts 2 and the plates 4 of the top rails 3 areprovided with vertical slots 7, and formed in the edges of these slotsare half round notches 8 which receive the bolts utilized, in attachingthe pilot to the bumper beam.

The notches formed in the edges of eakclh t e notches formed in one edgeare directly opposite the straight portions of the opposite edge. Theslots formed in the post 2 are preferably approximately twice the lengthof the slots in the plates 4 in order that two or more attaching boltsmay be used between the ends of the pilot and the bumper beam. Thecorresponding notches of the slots in the plates 4 and the upperportions of the slots .7 occupy corresponding horizontal planes in orderthat the various attaching bolts may be readily seated in acorresponding horizontal row of notches when the pilot is adjustedvertically upon the bumper beam.

The bolts 9 used for attaching the pilot to the bumper beam pass throughelongated holes 10 formed in the front wall of said bumper beam andthrough the slots and I notches in the posts 2and plates 4, and thethreaded ends of these bolts receive nuts 11.

: pilot is provided with depending brackets 13 against which the upperportions of the posts 2 engage and these brackets are provided withelongated bolt holes which receive the lowermost bolts of the pairswhich pass through the slots in said end posts.

Formed integral with the end posts 2 and the plates 4 to the sides ofthe slots therein are rearwardly projecting lugs 14 which are adapted toenter corresponding apertures 15 formed in the front face of the bumperbeam, such construction being shown in our patent hereinbefore referredto, and being for the purpose of relieving the attaching bolts 9 fromstrains due to the weight of the attaching pilot. The construction justdescribed permits the pilot to be adjusted vertically upon the bumperbeam and when the nuts are tightened upon the bolts, the pilot isrigidly fixed to said bumper beam at the desired height and it iseffectually held in true central position.

The notches in the upper portions of the slots, being horizontallyalined, insures an accurate and corresponding adjustment of the ends ofthe pilot, and during such adjustment or when a bolt is shifted from anotch on one side of a slot to a notch on the other side, said-bolt ismoved from one end of the corresponding elongated bolt hole 10 to theother.

- The notches at the sidesof theslots are arranged so that for any onevertical position of the pilot the bolt through one vertical member ofsaid pilot, that is, either the end post 8 or plate 4 is at one end ofthe corresponding slot in the bumper beam, while in the adjacentvertical member of the pilot the bolt is at the opposite end of thecorresponding slot in the beam. Such arrangement permits verticaladjustment of the pilot, but prevents horizontal movement thereof sothat the pilot is always held in true central position. This arrangementalso prevails in the attaching means for the coupler pocket.

In Figs. 2 and 3 we have shown a coupler pocket 16 applied to thecentral portion of the bumper beam, and the attaching means for saidpocket is preferably the same as that utilized between the pilot and thebumper beam, namely, bolts which pass through vertically disposed slotsprovided in their opposite edges with half round notches. (See Fig. 2.)

The modified attaching means illustrated in Figs. 5 and (3 comprisesbolts 17 which pass through vertical slots 18 in the upper portions ofthe posts 2, and formed integral with and projecting rearwardly fromsaid posts are lugs 19 which are adapted to enter recesses 20 formed inthe front face of the bumper beam and the depending brackets 13.

In the modified form of attaching means illustrated in Figs. 9 to 11,inclusive, the attaching bolts 21 are provided with integral D-shapedcollars 22, which, when the bolts are properly applied, occupy thevertical slots and certain of their half round notches, which are formedin the end posts 2 and plates 4L of the pilot. In this construction theapertures through the bumper beam and its depending brackets 13 areround instead of oblong.

In Figs. 12 and 13 we have shown a pilot provided at its ends with aseries of integral horizontally disposed plates 23, the same serving assteps to permit trainmen to readily pass from the ground to the bumperbeam, or vice versa.

By our improved construction it is pos sible to produce a comparativelylong pilot, or one having a base length of three or four feet, as easilyas a comparatively short pilot, and by forming the pilot in two or moreparts, the foundry work is greatly simplified and cheapened.

It will be readily understood that owing to the irregular shape of apilot it is a comparatively difficult matter to cast the entire pilot inone piece, and the percentage of loss in producing large one piece andirregular shaped castings is comparatively great.

By virtue of our improved construction the pilot sections which arecomparatively small can be readily cast, and when said scctions areproperly connected, a. pilot is produced which is, in effect,practically as strong and rigid as a one piece structure, and in caseeither section becomes broken,

it can be replaced and the unbroken section continued in service.

Our improved attaching means, namely, the bolts passing through thenotched slots, permits the pilot to be readily adjusted in verticalposition upon the bumper beam, and as the corresponding notches of thevarious slots are horizontally alined, both sides of the pilot can becorrespondingly moved without the necessity of repeated measurements ateither end of the pilot.

It will be readily understood that minor changes in the size, form andconstruction of the various parts of our improved loco motive pilot maybe made and substituted for those herein shown and described, with outdeparting from the spirit of our invention, the. scope of which is setforth in the appended claims.
